The side members C", 'C2x l-t ar C3 is bored, or otherwise shaped '-5" are each cast with an upwardly extended to provide a bearing for this shaft, the 110 vwholeextending through the frame piece, andfcarrying the pinion I-l2 at the other end. 'lhis pinion H2 lies between, and engages with both of the aforesaid gear wheels F, F Ion the axle. Thus, as will be seein' the motor, and all of its important adjuncts,

are rigidly mounted' on the truck body or v frame, in contradistinction withthose mech- Vanisms in which the motor 1s connected to intermediate gearing, is allowed to rise :and fall upon t` e spring supports which bear on the axle boxes.

To transmit the power uniformly and smoothly at all times 'from the gearing to th'e'axles, I employ the following device, whereby the rising and falling of the parts, including thecountershaft and its pinion H2, will not produce serious disadvantages to rise and fall relatively in the transmission of the power to the wheels F, F as it would if they were rigid with the axles, and vertically stationary as in the earlier common constructions: 'I indicates a ring or open centered disk, which is placed around the axle, and lies in vertical planes between-the track wheel and the gear Wheel F or F. It is connected to the gear wheel (F for instance) by means of links J, J, each of which ispivoted at one end to the wheel F, and attle'other end to the ring I. .The ring, in turn. is connected flexibly to the truck wheel by means of the links K, K. The pivots orV hinge pins which engage with the links K, K, are connected thereto by a ball and socket joint. Such a pin or pivot is shown at 7s. it having a ball like head 7c. The link has a socket at k2 in which the ball or pin is fitted. As a consequence the car axle is permitted to the body without any cramping or binding of the piv- .otal connections of the links. as the latter can relatively swing out and in and still maintain the proper connection between the parts.

The bearing bosses *2 have central apertures, as shown at f, which are larger than the axles -D, and consequently the bosses. and all of the parts rigidly connected therewith, to wit, the truck body and motor, and the gearing, can rise and fall to the extent permitted by these enlarged apertures 7.

The central opening in the ring I is considerablylarger than the. axle in the bearing piece F 2, and consequently permits of the vertical playing of axle and body, as. to each otherthat is demanded. The ring,v although havingno central support, is at all times held in proper position by the links, there being ofcourse a slight playv vertically vand horizont-ally, to conform to the vertical movements vof the parts connected by it.

By having all of the toothed gears mounted in iixed relations, that is, in such a way. that there is no movement of their axes rela tive to each other, I Secure several important advantages in a locomotive of this char'- acter. The armature is always in the s"une relation to the gearing throughout th ain. The wheel F is at all times driven thereby with the same etliciency as the wheel F: and

it is well known that where the power can be thus collected and vuniformly applied to bothaxles of a car, or truck, the tractive etticiency is correspondingly increased, there vbeing a constant tendency for one or other of the axles, and its truck wheels, to bound up or escape from the track, and at all such instants the traction or pulling power is correspondingly decreased.

The connecting devices or gearing which I have described as being interposed be'- tween the motor and the two axles of the truck supporting the motor constitute a uniyersal connection between lthese parts, that 1s to say. the gearing allows a rising and falling of the axles flative to the truck, and consequently relative to the motor, without disturbing the direct and constant connection under 'any working condition between the motor and both axles. 1

By taking the weight of the motor, and all of the gearing olf from the axles (excepltso far as it is transmitted through the spring El disastrous action upon the track rails is so reduced that I find that a veryA much lighter rail can be used, all other things being equal. and the cost of an entire railway system can be .proportionately reduced.

In the vehicle as a whole, which is selected for an illustration, there are two trucks corresponding to that above described. They are flexibly connected together and to the superposed body as follows: L, L' are cross bars.' There are two of these for each truck, the pair constituting a brace, and each formed of angle iron. They are bolted to the upwardly extended upright parts c ofthe truck frame. Atthe center transversely-of each brace 'there is a pivoting device secured. Each' of these consists of plates M, M', they corresponding to the fth wheel of'a vehicle, that is to say, proriding extended hinging bearing and wearing surfaces. 'Each part M, M' is formed with a base part m one of which is securedl 'pl'.vingthe draf: that "relatiyely i-lgzlhaaforesaid crossfbarbr. braces L and i -,T lates 2M," Alf vare.'f ofriiied withcircular ri fmf vand"'fgrooyes "1n-7, the 4'ribs ,of one entering into they grooves of` theyother.

Thetlraft is transmitted from or to the vehicle y peculiarly formed draw-bars. There is one of theseat each end. and each isindicated by X. yIt is extended inward, andA is free ofthe truck until it reaches the cross bar or brace L, L. It is pivoted to the latter, therebeing a pivot ear n secured to the cross bars, andto this the draftbar secured vby thevertical pivot An. By apat @the points indicated, high and at the point of p'v-'o'tal connection of the truck to the body,

the truck1 is vnot seriously interfered with linlitsoscillations on the track. Audit is left to `flexibly accommodate itself to different variations that are required in its path. Y. l l

' The vtwo vtrucksfare connected together principally by the` frame at the bottom of the body. This Jframe consists of the angle irons O, O bent to form the upper horizontal parts or platforms 0, and the central drooping parts 0. Theselsill bars are connected at the ends by cross girths O. At intermediate lines they are connected bythe cross angle bars O2,;O3. To the centers of the latter are secured the base parts m of the pivot piece M.

Above the 'central' drooping part of the frame is formed thecab or housing for the motorman, this containing also the manual devices by which the brakes are applied, and that by which the'current is cont-rolled in its passage to the motors, and the other devices ordinarily required for operating a vehicle of this sort.

Over the end parts of the frame there are arranged the casings or boxes P, P for the storage batteries. The cells are arranged within this housing in the way illustrated. They are in two horizontal tiers, the lower being indicated by p, and the upper by p. The cells are placed in boxes-or chests as at p2, p3. The boxes or receptacles p3 rest upon the oor of the car body. Above these lower cells are placed the supporting bars p4, upon which rest the cells and the boxes of the upper tiers.` The cros's bars p* are held by a frame Q, the side bars q, g of which lhold the cross bars. When building up the battery the bottom cell boxes at. p are first arranged on the car; then the frame Q is placedfover them, yand, then `-theuLppewr ,Clll @Ul BOXES at Per@ Pllceld :Ont-.hej bills p4. and thefhousingi's closed."` R indicates the controller vinterposed,'between the battery andthe motors. the "de tailsot wliichcan be of anysuitable sort.. The cells vof the., batteryfare` arrangedjvin sets. and thev electricconnections betiijeen these cell sets and the controller are such that the cell sets can be eitherr all in series, or all in multiple, or so that each half of them will have its component sets in series, and the two halves in multiple. l

The brake mechanism is indicated by S.

a wedge shaped brake shoe arranged between the peripheries of two of the track wheels. There is one of these shoes onv each side of the truck. They are operated by means of a hand wheel s in the motornians cab T by the followingdevice: They shoes are secured to links or draw rods s2 ,which are pivoted to bell crank levers s3. and the latter are connected by the links s* tothe equalizingv bars .95. 5". .s6 are links connecting the equalizing bars to the levers si. sg, respectively. The lever .9S is pivoted at one end to the frame-work. and at the other 'end is connected by a link 8, to the lever s. The latter has a chain s1, 0ne-end of which can be wound upon a winding shaft s, mounted on the underside of the framework. The shaft s has a ,worm gear 812, with which the worm pinion .S13 meshes. This worm is on the shaft s mounted on the standard 815. in 'the cab, and secured to the hand wheel.

The central longitudinal part C3 of the truck frame can at the points adjacent to theaxles of the track wheels be either constructed as shown in Fig. 7 with vertically elongated slots or chambers open at the bottom, or it can be formed with closed tubular axle' chambers. as shown in Figs. 9. 10 and 11, there being below the main part of the casting C3 separable pieces which can be bolted to the main part. Here the tubular boss or bearing at F2 tor the gear wheel which surrounds the axleis of a nature shown' in these Figs. 10 'and l1; in the other case this boss or bearing may be provided by bolting suitably shaped parts to the sides of the longitudinal frame parts C3. f Space is economie'd to the utmost because of the relative arrangement of the trucks and body parts, the trucks being respectively under the ends of the relatively elevated parts of the body, the cab or central part being depressed to lines below the top of the motor trucks. the frames of these trucks being inclined or curved downward toward their inner ends, and conforming to the contour `of the bottom of the depressed part of the body.
